Pepperl+Fuchs Podcasts

Pepperl+Fuchs’ TechTalk helps listeners gain an insight into modern automation technologies by focusing on AS-Interface (Actuator Sensor Interface) and its associated safety technology, Safety at Work. TechTalk covers topics that range from hardware selection to installation and maintenance. Control engineers familiar with AS-Interface will get the latest news on specification enhancements, hear about new products, and familiarize themselves with established and cutting-edge troubleshooting methods, tips, and tricks.  Users who are interested in applying these technologies will learn what it takes to set up an AS-Interface system, how Safety at Work improves safety systems, and why those technologies have the potential to save time and money during all phases of a project.

Most modern installations use AS-Interface gateways that are Ethernet based.  More specifically this means PROFINET and EtherNet/IP.  These gateways are also available with an integrated safety controller.  Tim and Helge discuss why this integration of the gateway with safety functionality is advantageous.
As far as AS-Interface power supplies are concerned, most installations utilize 4 A or 8 A power supplies.  While decoupling can be located in an external device or in the gateway, it is still most common to have the decoupling circuit inside the power supply.
